The AUX 2.5 Ton Concealed Duct Type Inverter Air Conditioner (Model: ALTMD-C30/NDR3MA / ALT-C30/NDR3A) is a premium, high-capacity centralized cooling system designed to be completely hidden within a false ceiling or drop plenum. Blending seamlessly into modern architectural layouts, this system combines variable-frequency DC Inverter technology with robust high-ambient protection, making it highly effective for large villas, open-plan apartments, or commercial offices experiencing intense summer heatwaves.

Advanced DC Inverter Efficiency

•  Powered by a high-efficiency variable-speed rotary compressor. Instead of cycling fully on and off (which wastes power and causes temperature swings), the inverter system dynamically scales its motor speed to match the real-time thermal load of the property. This guarantees ultra-stable comfort and significant energy savings.

High-Ambient T3 / Desert Architecture

• Explicitly tropicalized to endure severe climate conditions. The system safely handles continuous heat extraction under extreme head pressures, running reliably even when outdoor ambient temperatures climb past $52^\circ\text{C}$.

High External Static Pressure (ESP) Control

•  Features an adjustable static pressure capability reaching up to 160 Pa. This provides the necessary mechanical force to push air evenly through complex, long duct networks and multiple air diffusion grills without losing volumetric velocity.

Built-in Mechanical Condensate Pump

• Comes factory-equipped with a built-in drainage pump capable of lifting condensate water up to 70 cm vertically. This simplifies installation parameters in tight ceiling clearances and safely avoids structural water pooling.

Dual-Option Air Intake Flexibility

• The internal air handler unit offers a highly adaptive structural setup, allowing the return air duct to be mounted from either the back or the bottom of the chassis depending on the false ceiling shape.

Next-Generation Eco-Friendly Design

•  Built around an optimized thermodynamic loop using eco-friendly refrigerant (batch/region dependent, prioritizing R32 or R410A). It features a high thermal conductivity index, allowing fast room pull-down times while minimizing global warming potential.
